To (LZZ w/wnt ntay concern:

Be it known that 1, WILLIAM E. G-ILDEA, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Closures for Bottles, of which the following is a specification.

My invention relates to closures for bottles, jugs, and the like; and its primary object is to provide a novel and highly useful device of this character which will permit of the contents of the bottle being freely withdrawn and which will prevent the bottle from being refilled, thereby defeating any attempt at selling a substitute for the original article.

A further object of the invention is to provide a device of the above-stated character which is simple of construction, cheap to manufacture, durable and eflicient, and which has its parts so constructed and associated that all liability of the closure becoming broken or inoperative is obviated.

The invention consists in the construction, combination, and arrangement of parts more fully hereinafter described, claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which Figure 1 is a central longitudinal sectional view of the upper portion of a bottle, illustrating the application of my improved closure. Fig. 2 is a detail top plan view of the valve-gi'iard. Fig. 3 is a detail elevation thereof. Fig. 1 is a sectional view on the line 4 4:, Fig. 1. Fig. 5 is a detail perspective view of the valve, and Fig. 6 is a detail plan view of the ring for retaining the valveguard in its position within the neck of the bottle.

Referring to the drawings by referencenumerals, 1 designates a bottle provided with a neck 2, having communication with the interior of the bottle by means of a passage 3. The lower end of the neck is reduced, as at 4-, to provide a valve-seat 5, which has its upper face inclined downwardly and outwardly, as at 6. Mounted upon the seat is a valve 7, which has its under side inclined upwardly and inwardly to correspond to theinclination of the seat 5. The valve has secured to its under side a pendent member 8, which is adapted to retain the valve in its normal position upon the seat 5 and which is adapted to guide the valve in its movement toward and away from said seat. The pendent member 8 is adapted to work within the passage 3,

whereby to guide the valve, as before mentioned, and said member is grooved longitudinally, as at 9, or star-shaped in cross-section to permit the liquid to flow, when the valve is unseated, through the passage 3 into the neck 2. The upper end of the valve 7 is recessed, as at 10, for a purpose to be presently described.

Mounted within the upper end of the neck above the valve-seat 5 is a guard 11. This guard is of a diameter to permit it to be readily inserted within the neck, and it is provided with an annular groove 12, adapted for the reception of a spring locking member or key 13. The locking member or key 13 is of such a nature that it may be compressed to permit the guard to be inserted within the neck, and it is adapted when opposite an annular groove 14 in the neck to spring thereinto, whereby the valve is securely locked in applied position against accidental displacement or unauthorized removal. The guard has its upper end chamfered, as at 15, and is provided in its lower half with a chamber 16, opening at its lower end, as fully disclosed in Fig. 1 of the drawings. Openings or passages 18 extend from the chamfered portion 15 to the chamber 16, whereby the liquid may be poured freely from the bottle. The guard is provided with depending members or lugs 19, with which the valve 7 is adapted to engage when the bottle is canted to limit the movement thereof. The lower ends of the lugs 19 are situated a su'l'licient distance from the valve-seat 5 to permit the valve to move a sufficient distance when the bottle is canted to permit the bottles contents to be freely poured.

The operation of the improved closure may be stated in the following manner: After the bottle has been supplied with liquid the valve 7 is inserted in applied position. Then the guard 11 is inserted within the neck in a manner that is apparent to those skilled in the art, and to preserve the contents of the bottle a cork 20 is applied above the guard 11. When it is desired to remove the contents of the bottle, the cork 20 is first extracted and then the bottle is canted. The canting of the bottle will cause the valve 7 to unseat and permit the liquid to flow through the grooves 9 of the pendent member 8 into the bottle-neck above the valve-seat 5. From this point the liquid will flow around the valve 7, through the spaces intersecting the lugs 19, and thence into the chamber 16, from whence it flows through the openings or passages 18 out through the mouth of the bottle-neck.

After the bottle has been righted or brought into a horizontal position the valve will gravitate onto the seat 5 is apparent from the inclination of the open- 1 ings 18 that any attempt to insert an instrument below the guard and valve 7 will be defeated, for the reason that the inclination of the passages 18 will direct the instrument into the depression 10 in the valve 7, thus obviating any liability of an instrument being in- I serted so as to prevent the seating of the cham't'ered edge, and with lugs pro ecting from valve.

From the foregoing description, taken in connection with the accompanying drawings,

proved closure will be readily apparent without requiring any further extended explana- It will be seen that the device is simple 1 tion.

of construction, that said construction peri mits of its manufacture at small cost, and that it is exceedingly well adapted for the purpose for which it is designed.

Having thus fully described the invention, what is claimed as new is A bottle havi ng a neck provided with a valveseat and with an annular groove above said seat, a valve adapted to engage said seat, a guard within the neck above the valve, said guard comprising a plug provided with a solid upper portion and a base-chamber, said plug also being provided with an external annular groove contiguous the point of junction between the chambered and solid portions, and further being provided with a cham'fered upper edge and inclined passages extending from the chamber through the solid portion and its base beyond the chamber and forming j stops for the valve in its opening movement, the construction and advantages of my imand means engaging the grooves to lock the guard within the neck.

In testimony whereof I affix my signature in presence of two witnesses.
